Goaltending
This one is kind of a cheat as well, because most teams have this question too. How many goalies do we go into the year with and we almost know we can get a good season out of them? Maybe four or five league wide? Shesterkin, Vasilevskiy, Hellebuyck and Saros? Who else? Everyone else will seemingly have their ups and downs. That's the goaltending position for you.
But it is a big "if" the Capitals face. What happens with Darcy Kuemper? Do the Caps bring him back? If he doesn't return, who is the backup? Or potentially who is the starter.
I know a lot of fans out there are saying, "Hey dummy, Charlie Lindgren is the starter!" which you would have to think is true going into next season. Are you really that confident in him? He is a thirty year old, turning thirty-one in the middle of next season, who has never proven to be a long term option. Can he be? Yes. Why not? But he is not one of the four that we talked about earlier who you can almost bank on having a good season.
Lindgren has not proven he is a long term option yet. Until he does that it's a question. It's an "if". What happens if Lindgren can't do what he did last season?
